Hierarchical Data Format (HDF) 5 is a file format to organize large amounts of data within a single file [1, 2]. The file is broken up into datasets (typed multidimensional arrays) and groups (containers that can hold other datasets or groups). Both datasets and attributes may contain attributes about the data. HDF5 data will typically use a .h5 extension.
HDF5 Usage within Imatest
HDF5 files store data as binary chunks of data. This enables the storage of images within the results file, unlike JSON or CSV outputs.
HDF5 outputs were introduced in Imatest 22.2 with the stray light analysis feature.
Interacting with HDF5 Files
The HDF Group offers HDF® View, a free (with an HDF Group account) HDF5 data viewer .
